You cannot bind code that refers to objects in the Writable Static Area and has been prelinked, and code which refers to objects in the Writable Static Area and has not been prelinked, in the same program object. This is because the z/OS® prelinker and the binder use different methods to manage the Writable Static Area. The z/OS prelinker removes relocation information about objects in the Writable Static Area, making them invisible to the binder. The binder keeps relocation information and manages the Writable Static Area in the binder class C_WSA.
